    摘要： An image forming apparatus is used in conjunction with a signal generator for producing an image signal representing an image to be recorded. The apparatus includes a device for forming a visible image with visible material on an image bearing member. The image is represented by the image signal produced by the signal generator. A time signal is also generated by a time signal generator and a measuring circuit measures the time signal so generated as a function of the production off the image signal by the image signal generator. Finally, a warning signal that indicates insufficiency of supply of the visible material for forming an image properly by the image forming device is produced on the basis of measurement of the time signal by the measuring circuit.

    摘要： A developing apparatus having a container for containing a one component developer, and a rotatable developing roller disposed facing an image bearing member to carry developer from the container to a development zone where it is supplied to an electrostatic latent image carried on an image bearing member. The developing roller includes a metal base member and a resin coating layer thereon in which fine conductive particles are dispersed. The developing roller has a surface including an end region adjacent an end of the roller, and an intermediate region. In the end region, the base member is not roughened and the resin layer is not provided. In the intermediate region, inside the end region, the base member is roughened and is coated with the resin layer. A sealing member is provided for preventing leakage of the developer from the container at the end of the developing roller, the sealing member being faced to the end region of the developing roller.
